To find Lucas's total sales, you can use the information given about his commission and the amount he earned. Here's how to calculate it:
Let X be Lucas's total sales.
Lucas earns a 22% commission on all sales, which means his commission is 22% of his total sales. In mathematical terms:
Commission = 0.22 * X
Given that Lucas earned $840 in commission, we can set up the following equation:
0.22 * X = $840
Now, to solve for X (his total sales), divide both sides of the equation by 0.22:
X = $840 / 0.22
X = $3,818.18 (approximately)
So, Lucas's total sales were approximately $3,818.18.
